Title: Improvements in a power transmitting device and its application to a differential gear
IPC: F16D41/00
Filed: 1929-07-24
Abstract: 316,312. De Lavaud Holdings Corporation, Ltd., (Assignees of Lavaud, D. S. de). July 27, 1928, [Convention date]. Clutches, free-wheel. - A clutch comprising rollers &c. 5, Fig. 3, which prop against inclines 4 in both directions so as to prevent driven member 2 from overrunning driving-member 1<a> is provided with retaining-means to limit the relative displacement of the rollers to allow freewheeling. Arrangements with twin clutches are described forming differential gears which allow overrunning of either member 2, the cages 7 being connected by a spring-pressed ball 8, Fig. 2, allowing limited relative displacement. When the cages 7 are free, the engine can be used for braking. When the cages are constrained, coasting of the vehicle is obtained. Backward coasting is prevented. The constraint is applied by braking a member 11 which causes a ball 13 to lock the cages to the differential casing web 1<b> without stressing the brake device. As shown in Fig. 5, the ball 13 moves through the web 1<b> so that when disc 11 is braked it engages a coneedged slot 10 in cage 7 and so retains both cages and allows coasting. When a spring plunger 24, Fig. 2, is withdrawn manually, the braking control ceases and a return spring 26, Fig. 1, functions to return disc 11, Fig. 5, so that ball 13 disengages cage 7 and engages a cone-edged slot 12 in brake disc 11, allowing engine to be used as a brake. During reversed driving of the vehicle, any braking control acts in the same direction as spring 26, Fig. 1, without effect, so that coasting backwards does not take place. The braking means comprise a corrugated disc 17, Fig. 2, carried in an annular recess in the disc 11 and having peripheral lugs 25, Fig. 1, projecting into the plane of plunger 24 and adapted to be engaged thereby when the braking control is to be rendered operative. Modifications are described in which the locking ball 13 moves radially of the gearing instead of axially. In other modifications the locking ball is replaced by rocking spring levers.and by spring plungers. In a form shown in Fig. 16, a finger 40 projects from the clutch cages through a slot N and oscillates freely when the engine is to be used for braking. To allow coasting, the rearward movement of finger 40 is prevented by a pawl 41 which is rocked into position by arresting an annulus 42 by a spring brake shoe 48 which is released manually. Constructions of band brake adapted to grip in both directions are illustrated. In further modifications, the braking control is exerted not for locking and so obtaining coasting, but for unlocking and so obtaining engine braking.

Title: Improvements relating to braking equipment for electric traction systems
IPC: B60L7/26
Filed: 1944-11-20
Abstract: 583,713. Braking for electric traction systems. WHYMAN, F., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 20, 1944, No. 23064. [Class 103 (i)] [Also in Groups XXXV and XXXVII] An electric traction vehicle equipped with means for electric regenerative braking and for mechanical braking controlled by fluid pressure has means provided for automatically bringing mechanical brakes into operation on failure of the regenerative braking to an extent dependent upon the electric braking effort immediately before failure. Current proportional to the field current of the regenerating motor M is supplied to the fixed coil Ts and current proportional to the armature current of the motor M is supplied to the moving coil Tc of a relay T (see Group XXXVII) the resulting force on the lever rl acting against the force applied to a piston VT by air pressure in a reservoir AR. If these forces are not balanced one of the contacts Ta, Tb is made, so operating one of the valves EV1, to admit compressed air from source AS to, or to exhaust air to atmosphere from, the reservoir AR. Thus the pressure in the reservoir is dependent upon the electric braking effort. On failure of the electric braking owing (say) to opening of the line circuit, operation of the overload and no-volt release P makes valves EV1, EV2 inoperative and permits valve EV3 to open. Pressure from the reservoir AR then operates a proportional valve V2 to admit compressed air to the brake-cylinders through conduit LB. A balanced piston valve V3 is connected to a proportional valve in the train vacuum brake system VB while a similar valve V4 is connected by a conduit LAV to the driver's valve of the locomotive compressed air brakes. Thus whichever system is most fully applied governs the operation of the brakes. The magnetic characteristics of the relay T may be designed to give a force between the coils Ts, Tc proportional to the electric braking effort.
